THE ANSWER is a simple, but revolutionary solution for contemporary water bottles. Keep your favorite Hydro Flask wide mouth bottle. Ditch 99.99% of the harmful tap water contaminants inside of it. We all love our double-insulated, wide mouth Hydro Flask bottles, but the fact that they don't include a filter, left us without an answer. That is, until we decided to create one.

Appropriately named THE ANSWER, this simple design lid/straw/filter device is a perfect fit for 32 oz and 40 oz Hydro Flask wide mouth water bottles. (More compatible bottles coming soon!) From waterborne pathogens, to heavy metals, fluoride and even trace pharmaceuticals, all are eliminated with our multi-patented filter media. Be confident that the only thing reaching your body is the purest water available. Our filter technology has been tested in 16 different countries, and they promise to remove some of the most contaminated tap water on Earth. Enjoy up to 75 gallons of pure clean water per filter. On average, we recommend replacing it once every few months if being used regularly.

Our American-made and American-tested filters outperform well known filtration brands any day of the week. You'll notice some of our biggest competitors do not even publish test results -- that's because their filters only remove bad taste and some chlorine (like that Brita pitcher you've become so skeptical of lately).

THE ANSWERcomes with one (1) Urban Filter and is also compatible with Epic's Outdoor Adventure Filter (but not recommended unless traveling). The Outdoor Filter is sold separately. Keep in mind, the Outdoor filter requires you to suck/squeeze a bit harder to get water through it, so we do not recommend using it for an everyday filter unless you live in an area with a very questionable public water supply to include pathogens. The Epic Outdoor filter removes 99.9999% of water contaminants as well as any waterborne pathogens like Giardia and Cryptosporidium and can be used on camping trips and as an emergency preparedness item with it's microbiological filter media.

Filter life: up to 75 gallons (285 liters) depending on average daily usage and water quality

Average recommended filter replacement: 3-4 per year

Epic PerformanceWhen we say Epic, we mean Epic. Our proprietary, multi-patented blend of filter media eliminates up to 99.99% of the harmful contaminants other filters leave behind such as chlorine, heavy metals, industrial and agricultural pollutants and trace pharmaceuticals - as well as reduction of fluoride. Why settle for anything less?

Epic ValueEnjoy up to 75 gallons (285 litres) of pure clean water per filter that will taste all the sweeter knowing you'll never pay for bottled water again.

Test and Approved WorldwideEpic Water Filters have been independently tested across the globe in both field and laboratory test in countries including the USA, UK, Australia and Japan. These rigorous processes are just another way we go well beyond what's required to deliver the cleanest, purest water possible.

Great filter and equally great service

I bought this filter through Amazon and when I did I mistakenly bought the filter for the 32 oz hydro flask instead of the 40 oz. The only difference between the two is the length of the straw. I only realized my mistake once the filter arrived. I emailed the company about my issue and they quickly replied and sent me a longer straw to match the size of my 40 oz bottle as well as a really nice sticker, free of charge. I was really impressed with their customer service. The filter is just as great. They work perfectly and the straw and filter are easily detachable so you can clean them easily but they won't come apart when you are out and about using it. The water at my university tastes a lot like metal but once I began using my water bottle with the filter the metallic taste is no longer there and the water actually tastes good now. The caps that come with the filter also work really good and are better made than the name brand hydro flask sports cap as I have one and these have a rubber cover on the bite valve making it more comfortable to drink water than with the hydro flask cap. Also when drinking water you can barely even tell you are using a filter. In all I am very happy with this product and will continue to purchase the filter replacements once these run out.
